Looney Tunes is a Warner Brothers animated cartoon series which ran in many movie theatres from 1930 to 1969. It preceded the Merrie Melodies series, and is both WB's 1st animated theatrical series and the 2nd-longest continuous animated series in any medium. The regular Warner Bros. animation cast also became known as the 'Looney Tunes' (often misspelled, intentionally or not, as 'Looney Toons').
